The only thing free is the heating/cooling system ### 1/5 — Contains only 1 simulation *2020-06-03* Its merely the cooling system youll look at... nothing else. Pay 6.00$ or delete the app Simple ### 1/5 — NOT FREE *2016-08-10, version 1.87* Sure...you can download it for free, but anything you wanna look at will cost ya money. Wanna see how the braking system works? $3.99. Do yourself a favor and don't waste your time or money on this app. Watch a YouTube video for free. ### 1/5 — Mr *2016-01-29, version 1.87* Poor quality, poor information!poor graphics..just poor ### 2/5 — Not free! *2021-08-28, version 2.0* Only one function is free. The rest is not. ### 4/5 — Great concept for visual learners *2015-11-01, version 1.83* This really provides the user freedom to learn how each sub system works together in unison. The only problem I had was trying to change the view. The zoom and rotation sensitivity was extremely high so I spent more time trying to get the component I wanted to learn more about, than actually reading about its functionalities. ### 5/5 — Great idea *2015-08-26, version 1.81* Like idea of interactive animatins. Very interesting and helpful. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
